Data Control Instructions Section 3-17
Example 2: Using TPO(685) Alone
When CIO 0.00 is ON, TPO(685) takes the duty ratio in D10, converts the
duty ratio to a time-proportional output, and outputs the pulses to CIO 100.06.
In this case, the control period is 1 s and the output limit function is enabled
with a lower limit 20.00% and an upper limit of 80.00%.
